Scope is good but being efficient and sustainable is even better.<\/p>\n

Alfons Zeestraten with chipped beet ready to go in the mixer wagons to be fed to lactating cows.<\/p>\n<\/div>\n

\u201cWe have a person on the pump at the pond and a person on the tractor and if anything goes wrong both of them can turn it off.\u201d<\/p>\n

The company\u2019s new operations manager, Adam Davis, who has a background in sheep and fertiliser industries, says the soil fertility levels on the farm are well-balanced and efficiently maintained.<\/p>\n

\u201cWith what we\u2019re doing I think we could turn around an old sheep farm in a year or two to top fertility, which is impossible using chemical fertilisers,\u201d he says.\u00a0<\/p>\n

\u201cAnd it\u2019s sustainable.\u201d<\/p>\n

He\u2019s enjoying the challenge of the new position after working part-time for the company for the past few years.<\/p>\n

\u201cEverything needs to be watched and little problems can become big problems very quickly if you\u2019re not on top of it.\u201d<\/p>\n

About 10% of the farms are planted in fodder beet each year, soaking up excess potassium from the soils.<\/p>\n

\u201cWe feed it to the cows that are milking at a total cost of 22c\/kg DM. That\u2019s grown, lifted, cleaned and chipped, then it\u2019s mixed with everything else in mixing wagons,\u201d Alfons says.\u00a0<\/p>\n

Lactating cows get 5kg DM of beet a day and it\u2019s reduced to 1kg DM\/day when cows are dry.<\/p>\n

\u201cBeet is a high-energy feed so it\u2019s a good feed for cows when they\u2019re milking but it\u2019s full of potassium and that is the one mineral you need to be cautious about when giving it to cows before they calve because of metabolic problems.\u201d<\/p>\n

Part of the lactating cows\u2019 diet is locally grown under contract \u2013 wheat and straw \u2013 as well as silage made on the farms, palm kernel, dried distillers grain from Australia, and molasses.<\/p>\n

\u201cWe try to be as self-contained as we can be. About 85% of what our cows eat is grown on our farms.\u00a0<\/p>\n

\u201cAnd we give the cows exactly what they need \u2013 the correct ration of protein, energy and fibre. Everything goes into the feed including all the minerals. We don\u2019t need to put a lot of lime on the farm because every day the cows are getting calcium which is then passed on into the organic matter which goes back to the paddocks.\u201d<\/p>\n

The cows have few metabolic problems, and if there are any they start looking at what\u2019s been fed.<\/p>\n

\u201cWe can fix it very quickly.<\/p>\n

\u201cThere is also a huge opportunity for us to balance high-protein grass with the right supplements. Protein is expensive so you don\u2019t want to waste it.<\/p>\n

\u201cA milking cow only needs 18% protein and grass can sometimes go up to 28% protein. And where does all that extra protein go when cows are grazing on pastures? Where it shouldn\u2019t.\u201d<\/p>\n

AI is for six weeks using Friesian genetics mostly from overseas.\u00a0<\/p>\n

Bulls follow AI for 12 weeks, going from farm to farm with breaks in between and don\u2019t seem to mind the barn environment. No CIDRs are used. The empty rate is 3% to 4%.<\/p>\n

\u201cYou can\u2019t get it any lower than 3%. We use a lot of frozen sexed semen and our conception rate with it this year is 65%, which is a good result.<\/p>\n

\u201cAnd because our in-calf rate is so good we have less wastage, so the average age of our cows is a year older than the national average so we get more productive years from them.<\/p>\n

\u201cWe don\u2019t want a large cow but we want a productive cow with a large capacity. Our cows still need to walk so they can\u2019t be huge.\u201d\u00a0<\/p>\n

Almost all heifer calves are reared, using robotic feeders. Surplus heifers have gone to the Chinese market in past years. Local beef farmers buy the bull calves at four days old.<\/p>\n

The farm has moved between sugar beet and fodder beet and now grows a hybrid between the two.<\/p>\n

\u201cSugar beet has very deep grooves so is hard to wash and we don\u2019t want our cows eating dirt. It\u2019s not good for them so this new beet works because the bulb is more uniform and smooth.\u201d<\/p>\n

The beet is lifted every three or four weeks, when the weather allows, and stored in heaps on concrete. It is then chipped every two to three days ready to be mixed with the other feeds.\u00a0<\/p>\n

The three farms could be sold separately and were set up that way in case debt levels became unmanageable.<\/p>\n

\u201cWe don\u2019t want to grow any bigger, we just want to do things better and bring in the children if they are interested and give them opportunities as shareholders.\u201d<\/p>\n

Besides improving per cow production, Alfons this season wants to start measuring how much grass they\u2019re growing after using the new umbilical effluent system for a year.<\/p>\n

\u201cI believe we\u2019re getting between 10% and 15% more growth but at this stage we\u2019re only guessing. I want to measure it.\u201d\u00a0<\/p>\n

Going to a fully housed system, as used in North America and Europe, is not where they\u2019re heading.\u00a0<\/p>\n

\u201cWe love and thrive off our hybrid system. When the conditions are right the cows go out to the pasture and they\u2019re on a mission. They don\u2019t run but they do walk very fast, and when the weather is bad or the sun hot, even if we opened the doors of the barns, they won\u2019t leave.<\/p>\n

\u201cIt\u2019s a win-win situation.\u201d<\/p>\n

Breaking down the costs<\/span><\/strong><\/p>\n

    \n
  • Cows dry for 45 days fed 11kg DM:<\/span><\/li>\n
  • 3kg straw @23c\/kg DM\u00a0<\/span><\/li>\n
  • 4kg silage @35c\/kg DM<\/span><\/li>\n
  • 3kg palm kernel @25c\/kg DM<\/span><\/li>\n
  • 1kg beet @23c\/kg DM<\/span><\/li>\n
  • Total feed cost $3.07\/day, $21.49\/week\u00a0<\/span><\/li>\n
  • For 45 days = $138.15\u00a0<\/span><\/li>\n
  • Barn cost $2000\/cow, $2500 including effluent system which is also used by the dairy.<\/span><\/li>\n
  • At 7% interest rate, paid off over 30 years = $137\/cow\/year<\/span><\/li>\n
  • Barn maintenance costs (electricity, rubber scrapers etc) $25\/cow\/year\u00a0<\/span>\u00a0= $162\/cow\/year<\/span><\/li>\n<\/ul>\n
